I was playing with the multiplayer plugin Lacewing Blue Client finally! I see now how diffrent it work now. When it's slow in connection there can go up to 5 sec before it do the same.
Other times it run smooth and fast like no one is online? Is there an option where you see some ping or how many is online. Sometime it crash and crash during some time online. How many use it today?
It seems to be a bug when the third 3 person join in then master app crash.
I would be nice if you could rent a server to test for a year , 5 month or 3 month testing online, Full Access? No Slow connection.
